Abstract

Objective To investigate the expression and function of GnRH and GnRH receptor (GnRHR) subtypes at the maternal-fetal interface.Design In vitro experiments using freshly isolated human trophoblast cells, decidual stromal cells (DSCs), and immortalized cell lines.Setting University teaching hospital.Patient(s) Placenta-fetal membranes from term deliveries.Intervention(s) Human trophoblast and DSCs were isolated, purified, and cultured.Main outcome measure(s) Expression of GnRH-I, GnRH-II, and GnRHR-I mRNA and protein in human trophoblast cell lines and tissues were evaluated by reverse-transcription polymerase chain reaction and Western blot. The effect of GnRH-I and -II on the production of select cytokines (hCG, interleukin [IL] 8, IL-6, matrix metalloproteinase 3, monocyte chemoattractant protein 1, vascular endothelial growth factor, soluble Fms-like tyrosine kinase 1, urokinase-type plasminogen activator, and plasminogen activator inhibitor 1) were measured by ELISA and normalized for protein content.Result(s) GnRH-I, GnRH-II, and GnRHR-I mRNA and protein were identified in trophoblasts and decidua. GnRH-I and -II stimulated hCG production by trophoblast and trophoblast-derived cell lines in a dose-dependent fashion (e.g., 2.8-fold, from 2.5 ± 0.5 to 7.0 ± 0.4 ng/mg protein per 24 h, for 1,000 nmol/L GnRH-I and 2.4-fold, from 2.5 ± 0.5 to 6.1 ± 0.6 ng/mg protein per 24 h, for 1,000 nmol/L GnRH-II) without affecting the production of other cytokines.Conclusion(s) Trophoblasts and decidua express GnRH-I, GnRH-II, and GnRHR-I mRNA and protein. GnRH-I and -II selectively stimulate hCG production by trophoblast cells without altering the production of select cytokines by trophoblasts or decidua. The role of GnRH-GnRHR signaling at the maternal-fetal interface therefore appears to be limited to the regulation of trophoblast hCG production.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
